PLAYER-PIANO PEDAL.

Specification of Letters Iatent.

Patented Aug. 1, 1916..

To (all whom it may concern:

Be it known that I, CHRISTIAN GULBRAN- SEN, a citizen. of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Player-Piano Pedals, of which tho-following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to pedal mechanism for player pianos and is concerned with an improvement in the way of providing a simple feature of adjustability, depending upon whether an operator finds it more comfortable or desirable to have the operating pedals stationed slightly higher or lower.

My invention is ilh'lstrated in the accompa'uying drawings in which Figure 1 illustrates a side elevational view showing my pedal mechanism applied to the suction bellows, the parts being shown in operative position; Fig. 2 is a view similar to Fig. 1, except that the parts are shown in inoperative position; Fig. 3 is a plan view of the device of my invention; and Fig. l: is an isolated view on a larger scale, illustrating in detail the inmrovement of my invention.

The stationary board of the operating bellows is illustrated at 5 and it will be understood that this board is fixed in some convenient way in the piano casing. As shown in Fig. 3, in this particular arrangement, two fixed boards 5, 5 are employed and each of these boards has secured thereto a bracket (3, to which bracket 6 a forwardly extending arm 7 is pivoted at 8, and these arms 7 may occupy the position illustrated in Fig. 1 or the position illustrated in Fig. 2. The forward ends of these arms 7 7 are connected by means of a connecting piece 9, which is provided with upwardly extending cars 10, 10, to which the pedals 11, 11 are pivoted. The upper end of each pedal isprovided with a pivot member 12 to which a link 13 is connected and the other end of this link is pivoted at 14- to a bracket 15 secured to the movable board 16 of the bellows. This linkage arrangement is such that when the arms 7, 7 are folded upwardly into the position shown in Fig. 2, the links 13- are also carried up and with it the pedals, all these parts being folded up within a small space, as illustrated in Fig. 2.

Secured to the top of the connecting piece 9 are the two hinge members 17, 17, this attachment being done in any suitable manner, for instance, by means of rivets 18. Each of the membu's 17 has hinged thereto at 19 a hinge member 20, and the two hinge members 20, 20, carry a strip or block 21, conveniently of wood. The under side of the connecting piece 9 is provided with feet 22 and the hinge member 20 is of such length that the block 21 may occupy a position under the feet 22 with the feet resting there on, as illustrated in Figs. 1 and 1. In such a case, it will be seen that, assuming the floor to be indicated by the line 23,the pedals will occupy a position higher than when the hinge members 20 and block 21 are thrown back into the position indicated in dotted lines. l Vith the block 21 in this latter position, the floor is properly indicated at 24L and the action of the attachment block is thus made clear.

If one desires the pedals slightly higher or lower for the purposes of comfort or the best position for playing, this may be accomplished by swinging the block 21 either under the feet 22, to boost the whole swinging frame, or by swinging the block back into the dotted position where it is inoperative and performs no function. Of course, when the pedal mechanism is folded up, as illustrated in Fig. 2, the attachment block merely hangs from its pivots and stands out of the way.

I claim as new and desire to secure by Letters Patent:

1. In pedal mechanism, a swinging frame, pedals mounted upon said frame, and means carried by the frame and adapted when in one position to lie under the frame with the frame resting thereon and when in the other position to allow the frame to swing farther about its axis.

2. In player piano pedal mechanism, a swinging frame, pedals mounted thereon and connected with the movable board of an operating bellows, and a block carried by the swinging frame and adapted to occupy two operative positions, one under the end of the swinging frame with the frame resting thereon and another in which the swinging frame may swing farther about its axis.

3. In player piano pedal mechanism, a swinging frame, pedals mounted thereon and connected with the movable board of an operating bellows, feet 011 said swinging frame, and a block carried by the swinging frame and adapted to occupy a position under said feet with the feet resting thereon and another position wherein the frame may swing farther about its axis.

l. In player piano pedal mechanism, a swinging frame, pedals mounted thereon and connected with the movable board of an operating bellows, feet on said swinging frame, and a block hinged to said swinging frame and adapted to occupy a position under said feet and with said feet resting upon it and another position wherein it is swung back so that the frame may be swung farther about. its axis.

In Witness whereof, I hereunto subscribe my name this 28 day of October A. D., 1914:.

CHRISTIAN GULBRANSEN.
